"My works" page, admin user sub-lists, mobile compatibility, and user behavior audit.
New Features
"My works" page: singular URL, simplified list, dedicated edit page (read-only canvas + re-review + danger-zone delete), with end-to-end tests.
Admin user read-only sub-lists: 5 pages and APIs for credit ledger / invites / favorites / following / followers (one-click jump from the user detail page).
User behavior audit + activity stats: records login / logout / check-in etc.; the admin backend shows activity trends (DAU).
Experience Improvements
Work / example detail pages show a preview image placeholder first, then switch to the canvas when ready, for a smoother experience.
Homepage tag hints dropped their prefix and rounded-background, fitting into the gray-card dashed separator.
Bug Fixes
Fixed front-end and admin mobile compatibility (usable in portrait on phones), verified on iPhone SE / 12 and Pixel 7.
